The DAR has opened up their online Genealogical Research System to the public. Up to now it was only accessible by members of the DAR. It includes the Ancestor Database which contains the lineage information from most of the verified DAR applications - they are still in the process of getting all of the application information online.
Another DAR search link. The GRC -- the Genealogical Records Committee of the DAR. There are more than 35 million names recorded here, including 607 Bourne's in New York, alone (and thousands in the US, though the search results max out at 1,000).
WWII Enlistment Records from the National Archives (NARA). There are more than 9 million records here of just about every man and woman who enlisted in the Army during the period of World War II (1938-1946).
